We propose a scheme to realize stable propagation of linear and nonlinear surface polaritons (SPs) by placing a N-type four-level quantum emitters at the interface between a dielectric and a negative-index metamaterial (NIMM). We show that in linear propagation regime SPs can acquire an active Raman…
